Stacksaga Dependencies and Relations

The above diagram shows all the main dependencies that should be added to your project and their relations of the StackSaga umbrella project.

As per the diagram, stacksaga has two main implementations called
- stacksaga framework (synchronous implementation)
- stacksaga-kafka framework (asynchronous implementation using Kafka as the message broker)
If you are using stacksaga framework(synchronous implementation), mainly you need to add the dependencies to the flowing services,
- orchestrator-service
  In the orchestrator-service, you need to add three main dependencies as follows,
  - stacksaga-spring-boot-starter
  - stacksaga-database-support (you can choose any one of the database support modules as per your primary database)
  - stacksaga-environment-support (you can choose any one of the environment support modules as per your deployment environment)
- agent-service
  The dependency that should be added to the agent-service depends on which database support dependency is used in the orchestrator-service. For instance, if you are using stacksaga-mysql-support in the orchestrator-service, you need to add stacksaga-agent-mysql dependency to the agent-service.
If you are using stacksaga-kafka framework(asynchronous implementation), mainly you need to add the dependencies to the flowing services,
- orchestrator-service
  In the orchestrator-service, you need to add three main dependencies as follows,
  - stacksaga-kafka-spring-boot-starter
  - stacksaga-database-support (you can choose any one of the database support modules as per your primary database)
  - stacksaga-environment-support (you can choose any one of the environment support modules as per your deployment environment)
- agent-service
  The dependency that should be added to the agent-service depends on which database support dependency is used in the orchestrator-service. For instance, if you are using stacksaga-mysql-support in the orchestrator-service, you need to add stacksaga-kafka-agent-mysql dependency to the agent-service.
- client-service(target-service)
  In the client-service(target-service), you need to add the stacksaga-kafka-client dependency to be able to consume the messages and send the response back to the orchestrator-service with stacksaga specifications.

stacksaga-database-support and stacksaga-environment-support can be used for both stacksaga and stacksaga-kafka frameworks as a shared module. for instance, if you are using stacksaga-framework(synchronous implementation) and stacksaga-kafka-framework(asynchronous implementation) in your project together, you can use the same stacksaga-database-support and stacksaga-environment-support modules for both.
